SAS Statistical Business Analysis Using SAS 9: Regression and Modeling — Question 24

Which method is NOT an appropriate way to score new observations with a known target in a logistic regression model?

Answer options

• A. Use the SCORE statement in the LOGISTIC procedure.
• B. Augment the training data set with new observations and set their responses to missing.
• C. Augment the training data set with new observations and rerun the LOGISTIC procedure.
• D. Use the saved parameter estimates from the LOGISTIC procedure and score new observations in the SCORE procedure.

Correct answer: C

Explanation

Option C is incorrect because augmenting the training dataset and rerunning the LOGISTIC procedure is not needed for scoring new observations. The other options correctly outline methods to score new observations using existing models or data.
